Re: PID Control
A PID is a useful tool, but if you don't know why the jerking and wheel spinning are taking place, you may be applying a SW band-aid rather than solving the problem. Similarly, there are other approaches that are simpler and won't introduce instabilities like an improperly tuned PID can/will.
For example, if the drivers are just too aggressive with the stick, you can either let them practice until they learn not to spin and bounce, or you can lower the acceleration in the code. Both are simpler and more effective than a PID.
See if you can identify the problem more clearly, and ask again.
